I have no idea if they will win the case, as I have no clue what the actual evidence is, but they could certainly try the case even without her testimony. There are forms of evidence other than direct testimony, so yes, it is entirely possible that they will still try the case, but I would think they would have a much better chance of success if they got her to testify before a jury AND her claims are credible. In any event, that has nothing to do with the question I posed to you (you seem to be confusing criminal cases with civil cases). In FACT, you haven't answered a SINGLE question yet! You, sir, are no gentleman!
